What is Sefer ha higayone ?

עֲלֵי הִגָּיוֹן בְּכִנּוֹרתהילים צב:ד

אמרו ערך מלאכת ההגיון אל השכל כערך הדקדוק אל הלשוןרמב״ם, מילות הגיון

Rabbi Moshe Chaim Luzzatto zt“l, the Ramchal, wrote the Sefer ha higayone – The Book of Logic – in Amsterdam in the 1730s. He was a teacher at the yeshiva Ets Haym. His talmidim were often children of Marranos. They needed a method and higayone – logic – is the science of the formal rules of reasoning.

The word higayone that comes from Tehilime, was given by Moshe Ibn Tibbon when he had to translate a book that the Rambam wrote on logic in the Arabic language : the Makalah Fi-Sina-At Al-Mantik. The Malbim and the Vilna Gaone have also written books on higayone.
